This is the system I have... c.a. 1940 Detroit

My question is this: any parts around? also, could the wood sashes be saved and used in a modern balance/track system?

yes, sorry... I had not taken the window track out of the casement last post... If these are salvageable, I need to find a way to better fasten the spring loaded side to the wall. There are recessed screw guides/eyelets; but several have popped through the track, others have widened the recessed screw nubopenings and the fastening screw simply pulls through.

Sorry to annoy you... One more question.. (carrying un-lit cigar and wearing an old trench coat like Columbo)...

If I can keep them.. What type of lubricant, or none, should be used on the tracks/sashes?

This post is for upper corporate management...

These guys deserve all the "corporate love" you can give them.. Cut upper-management bonuses, salary and squeeze out a big pile of corporate cash and share it with your peeps.

At least match 401Ks to the max allowable by law and make sure there is pension and disaster money.. Be good corporate citizens and find a way to more than take care of your "Human Resources".

Thank You in advance in your attention to this matter; Jack

We have these windows in our home built in 1948. Same problem with the screws and metal cups pulling through. Small washers do the trick for the screws, and the cups are malleable enough that squeezing them gently in a vice can restore the little lip on the track. A couple of them just don't quite fit anymore but I moved those to the top of the outer track where I rarely move the sash. I have learned just to live with it.

The windows are made of hardwood and with proper maintenance will last another 80 years. The best part is they remove so easily for cleaning.

We also have these windows and I am glad I came across this post, because I haven't seen any other information on the Internet. We bought our house three years ago, and about half of the windows are these originals. Some of the cups were completely missing, so I used large washers and screws to keep the track in place. It takes a bit of time to adjust the screws so that the window will open like you want it to. The windows are double hung and the top windows don't really come down very easily (or at all because they have been painted shut), but it doesn't really bother us. I really like these windows and think they have a nice vintage charm to them. However, they are VERY drafty, so I am going to put in some interior "storm windows" (acrylic panels) to help with weatherization.

I've been restoring these windows for several years. I use a locking type nut. Just grind the ridges off the back side and insert wood screw. For the existing cups I use a 1/4" x 1 1/2" stainless steel screw. Then wax away.
